Pressed closely but not fused, e.g. leaves against a stem. aquatic plant A plant whose natural habitat is water, living in or on water for all or a substantial part of its lifespan; generally restricted to fresh or inland waters. arachnoid Cobwebby, from being covered with fine white hairs. arborescent Tree-like in growth or general appearance ...
In warm weather, the leaf has a flat oblong shape. As the temperature of the leaf drops, the blade curls inward, giving the leaf a tubular, cigar-like shape. Research on Rhododendron leaf thermotropism suggests that the curling response might help prevent damage to cell membranes caused by rapid thawing after a freeze.
The leaves are from 5 to 30 millimetres (3 ⁄ 16 to 1 + 3 ⁄ 16 in) wide and 10 to 118 centimetres (4 to 46 in) long. The leaf-like bracts are membranous, while the smaller bracteoles are either membranous or absent. [4] [5] The leaf bases are surrounded by up to 5 membranous sheaths called cataphylls, a specialised leaf. The bases of the ...
The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). [1] The edge of the leaf may be regular or irregular, and may be smooth or have hair, bristles, or ...
The slit between the leaves contains the meristem and produces flowers and new leaves. The leaves of Lithops are mostly buried below the surface of the soil , with a partially or completely translucent top surface known as a leaf window which allows light to enter the interior of the leaves for photosynthesis .
This is because the smaller plants do not have enough volume to create a considerable amount of heat. Large plants, on the other hand, have a lot of mass to create and retain heat. [5] Thermogenic plants are also protogynous, meaning that the female part of the plant matures before the male part of the same plant. This reduces inbreeding ...
The base of the leaf stalks (petioles) is greatly expanded. Smyrnium olusatrum, common name alexanders (or alisander) is an edible flowering plant of the family Apiaceae (Umbelliferae), which grows on waste ground and in hedges around the Mediterranean and Atlantic coastal regions of Europe.
A flowerpot, planter, planterette or plant pot, is a container in which flowers and other plants are cultivated and displayed. Historically, and still to a significant extent today, they are made from plain terracotta with no ceramic glaze , with a round shape, tapering inwards.
